Solution

The correct option is D

110minutes


The explanation for the correct option:

(D) 110minutes:

  • The chemical reaction is given as

2Cl-Cl2+2e-

  • According to Faraday's first law of electrolysis:

w=ZxIxtw=E96500×I×t

  • For 0.1mole of chlorine, the charge is 2×96500×0.1
  • Substitute the values in the equation

t=2×96500×0.103=6433seconds=107.33minutes=110minutes

We get,

  • t=6433.33seconds=107.33minutes=110minutes

Therefore, option (D) is correct. i.e., during the electrolysis of molten sodium chloride, the time required to produce 0.10 mol of chlorine gas using a current of 3 amperes is 110 minutes.
